OPENER.

Specification of Letters Patent.

Patented Oct. 11, 1921.

Application filed May 18, 1917. Serial No. 169,424.

To all whom it may concern:

Be it known that I, CONSTANT J. KRY- zANowsKY, a citizen of the United States, residing at Mount Washington, county of Baltimore, and State of Maryland, have invented certain new and useful Improvements in Openers, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to improvements in bottle-openers and particularly to that class of cap-removing devices which are'secured to a support.

Bottle-openers of this sort, as heretofore known, are subject to the disadvantage that they require careful and accurate positioning of the capped bottle-head; and further they require installation in a particular given position. There has been found, too, the additional objection that they tend, by virtue of their practically rigid character, to cause breakage of the bottle in case the first and comparatively slight force exerted thereon fails to remove the cap.

It is the object of the present invention to provide a stationary bottle-opener that ob viates the necessity of careful and accurate positioning of the bottle; one that may be secured to a support in any position; one that practically eliminates the danger of breakage; "and one that is, withal','simple in its construction and economical to manufacture.

A preferred form of bottle-opener constructed in accordance with this invention is described in the following specification and illustrated in the accompanying drawing, it being understood that changes may be made in the form, construction and arrangement of the parts without departing from the in vent-ion.

In the drawing Y Figure 1 is a perspective view of abottleopener constructed in accordance with the invention;

Fig. 2 is a plan view of the opener secured to a support;

Fig. 3 is a front view of the opener;

Fig. 4 is a central cross sectional view of the opener secured to a support, showing a bottle in place, ready for the removal of the ca and ig. 5 is a plan view (reduced) of the blank from which the opener is formed.

The opener comprises a bearer against which the top of the cap to be removed is forced and a remover for engaging the edge of the cap skirt. These element may be constructed in a varietyof ways, but in the preferred form shown they consist of two long flat bars 6 and 7, the opposite edges of which are parallel and are separated, with reference to a right line, by 'a space less than the diameter of the caps 11 tobe removed. One of these bars, the one, for example, marked 7 is offset inwardly to lie in a plane parallel to the plane of the bar 6, and the distance throughout which the offset relation extends is'substanti'ally greater thanthe diameter of the cap to be removed. For example, in the opener illustrated in the drawing, the bar 7 is offset f'ro'm' the bar 6 throughout a distance upward of three times the diameter of the cap. I V

The device is constructed to be secured to a stationary support, as, for exam le, the edge of a bar. The securing means may be of a variety of constructions. In the preferred form shown, the flat bars which constitute the bearer and remover are continued around rearwardly to parallel themselves and form two securing base portions 9 pro.- vided with screw holes 10 for screws 11, by means of which the device is secured to the stationary support 12. The base portions 9 are spaced from the bearer and remover, so

that the latter are supported a substantial distance out from the bar or other fixture.

Inthepreferred form the entire device 1s formed from'a fiat blank of the configuration shown in Fig". 5. This blank 1s a pressing formed from suitable material, preferably spring steel, and is slotted longitudinally, as clearly appears in the drawing, the

width of the slot being the distance separating the edges of the bars '6 and 7, as above described. The screw holes 10 are formed near the ends of the blank and the parallel edges of the slot are beveled, as shown at 13, Fig. 5, one edge being beveled on one side of the blank, the other edge on the other SIdG.

hand, at the sameltime."

. from the same. During this operation, one

of these bars, for example the one marked 7, 1S bent lnwardly, so that a considerable portion thereof-a portion substantially greater in extent than the diameter'of the caps-is made to lie in aplane offset from the plane of the other bar 6, and parallel thereto, this construction clearly appearing in Fig. 2. The device after suitable finishing is ready to be secured to the'stationary support 12by means of screws 11 passing through the holes 10, and it may be placed either in vertical position, as shown in Fig. at, or in horizontal position, or, if desired, at any intermediate angle. 1

In operation, the bottle 14:, sealed by a crown cap 8, is advanced head on toward the device until a portion of the top of the cap is forced against the upper portion of offset bar, or bearer 7, as shown in Fig. 4 By slight manipulation, the position of the bottle is adjusted so that the lower beveled edge of the other bar 6, the remover, is engaged by the edge ofthecap skirts A downward pivotal movement of the bottle as it is held againstthe bearer 7, will cause the cap to be forced off by the remover 6.

The extent of the distance throughout which bearer and remover 6' are offset from each other is several times greater than the diameter of;the caps to be removed, and it will .be seen that the relation between these two elements is constant between the terminal points of the offset portion. Consequently, within-this range it makes no difference at what point the bottle is pre-' sented for removal of the cap, as the removal may be effected at any point. As a result of theconstruction described, there is no necessity for accurate and careful positioning of the bottle, and the cap removing operation is readily and quickly carried out. Furthermore, the eliective extent of the cap.- engaging parts is such that, whendesired, a plurality of bottles may be accommodated simulta11eously,as, forexample, when a dispenser presents two bottles, one in each his not essential that the offset'bar be the lower'o11e,asshown in Fig. 4, although this .is the preferred arrangement, inasmuch as the mouth of the bottle uponbeing opened will be pointedupward, thereby preventing the contents from spilling out. Further, it

is notessential that the bottle be presented lnthe mannershown, as, if desired, it may be placed so that the edge of the barb serves as the bearer against which the top-of the cap is forced, the edge of the offset bar 7 engaging the edge of the cap skirt, and thus serving as the remover. Regardless, however, of the particular manner of presenting the cap for removal, the feature of the effective extent of bearer and removerbeing several times greater than the diameter of the cap, makes it unnecessary for an accurate positioning of the bottle, and the removal is always easily and quickly accom- 'plished. 7 As the bearer and remover are not rigid, in case the first and comparatively slight force exerted on the bottle fails to remove the cap, as may occasionally happen, the parts will, yield sufliciently to prevent the breakage that might ensue if the capped bottle were in contact with rigidmembers.

In conclusion, it will be seen that, in

addition to the structural advantages already pomted out, this opener 1s extremely simple and, owing to its simplicity and the fact that it is fashioned from a flat blank, it adds tothe advantage of readiness and effectiveness in use, the further advantage of economy in manufactur hat is claimed is: V 1. As a new article of manufacture, a de vice for removing crown caps from bottles and the like, comprising a pair of bars constituting a bearer against which the top of the cap to-be removed is forced and a remover for engaging the top of the cap skirt andhaving their opposing edges separated by a distance less than the diameter of the cap, said bars being in substantially the same plane near the ends thereof, one-of said bars being offset from the other throughout an extent substantially greater than the diameter of the cap, said bars being continued around rearwardly to form means whereby the device maybe attached to a support, 1

2. As a new article of, manufacture, a device forremoving crown caps from bottles and the like, formed from a flat blank and comprising a pair of bars constituting a bearer and a remover and having their opposing 'thetops of caps to be removed from bottles are forced and a remover for engaging the edges of the cap skirts, the effective extent of said bearer and remover being substan- V tially greater than thediameter of the caps,

the blank having its ends bent back on itself to form supporting wings for securing the whole to a support with the bearer and remover spaced a substantial distance therefrom.

4:. As a new article of manufacture, a device for removing crown caps from bottles and the like, comprising a pair of parallel bars having at their ends supporting Wing portions offset therefrom and parallel thereto, one of said bars having a portion offset from the other bar throughout an extent greater than the diameter of a cap, one of said bars constituting a bearer against which the top of the cap to be removed is forced, the other bar constituting a remover for engaging the edge of the cap skirt.

In testimony whereof, I have hereunto set my hand.
